The impact of fouling on the performance of filter - evaporator combinations

The aim of the present study is to characterize, experimentally, the effect of dust loading on coil performance for HVAC applications when employing different filter-coil combinations. The results of experiments carried out on different combinations of five types of filters of varying efficiencies (MERV4, 6, 8, 11 and 14) and four types of evaporator coils with depths and fin geometries under clean and fouled conditions, are presented along with the conclusions of the authors.
